APPARATUS FOR THE MULTIPLE OR MULTICOLOR DYEING HANKS OF. YARN Filed Dec. 1931 ATTORNEY INVENTORa Patented Mar. 21 1933 UNITED STATES PATENT OFFICE I FRIEDRICH FAIGLE AND CARL FAIGLE, OF HARD, NEAR BREGENZ, AUSTRIA APPARATUS FOR THE MULTIPLE 0R MULTICOLOR DYEING OF HANKS 0F YARN Application filed December 11, 1931, Serial No. 580,408, and in Austria May 23, 1930.

\Ve have filed application in Austria on the 23rd May, 1930, Germany on the 13th June, 1930, and Switzerland on the 25th September, 1931.

The present invention relates to apparatuses for the multiple or multi-color dyeing of hanks of yarn, and more particularly to a device for swinging and wringing or pressing hanks which are subjected to multicolor stepwise or intermittent dyeing operations (clouding or shading), wherein at any given time only a part of the hank is suspended in the dye bath contained in the dyeing vat.

The hitherto known dyeing apparatuses in which hanks of yarn are'swung to and fro by the aid of moving nieansiarranged inside of the dye bath, "and are wrung out or pressed by hand after the dyeing operation has been completed and the hanks have been lifted out of the bath, are only suitable for ordinary uniform dyeing but not for multiple or multi-color dyeing. In contradistinction to this the device according to the present invention is intended for multiple dyeing. According to the invention members such as rods, bars, tubes, rollers or the like for moving the suspended hanks in the bath are provided, which members are arranged above the bath so as to be capable of moving at any given time in the Same direction as one another or in opposite directions to one another, in such manner that the hanks which are only immersed in the bath to the desired extent are swung to and fro in the said bath and after the completion of the dyeing operation can be wrung out or pressed between the said members while being lifted out of the bath or after they have been lifted out of the bath.

Devices of this kind for carrying out the invention may be constructed in many different ways.

Some preferred constructional forms of devices according to the invention are illustrated by way of example in the accompanying drawing, in which:

Figs. 1 to 10 show diagrammatically various constructional forms of the swinging and wringing members provided above the dye bath, according to the invention, and indicate at the same time the mode of operation of the said members.

Figs. 11, 12 and 13 show in front elevation and end elevation, both partly in section, and in plan one constructional form of the device according to the invention.

Figs. 14 and 15 show in end elevation partly in section and in plan respectively a modified constructional form of the device according to the invention. 7

Figs. 16 and 18 show in plan and in end g elevation, partly 1n sectlon, respectively a further modified constructional form according to the invention.

Fig. 17 shows in plan a still further modified constructional form according to the invention, and

Figs. 19 and 20 show details indicating the method of supporting the members for swinging the hanks, Fig. 19 being a section taken on line ab of Fig. 13 and Fig. 20 being a section taken on line c l of Fig. .13.

As illustrated in Figs. 1 to 10, members in the form of rods 8 or the like for swinging and wringing the hanks St are provided, -wh1ch members may be of any desired cross section and may be grouped in different ways. The wringing out of the hanks or of the parts of the hanks which have'been dyed is effected by a pressing operation applied progressively from above downwards, for which purpose the aforesaid members .9 (rods, bars, tubes, rollers or the like) may be employed as indicated in Figs. 6 to 8.

For the purpose of rendering the operation of'pressing or wringing out more perfect, easily rotatable tubes P serving as pressing rollers may be provided on the rods horizontal position and moving the pressing members 8 or P respectively simultaneously downwards and towards one another (see Fig. 10).

3. By movingthe rollers W upwards and simultaneously moving the pressing members s or P respectively downwards and towards one another (see Fig. 10).

The mechanical means for effecting the swinging and wringing movements indicated in Figs. 1 to 10 is illustrated in the constructional examples shown in Figs. 11 to 18.

Figs. l1, 12 and 13 illustrate a constructional example in which the wringing or pressing rods 8 are mounted in guide bars F, F two of the hanks being shown in the position for swinging and two other hanks in the position for wringing.

The guide bars F, F which are suspended from the carriers T may be actuated by means of two pairs of connecting rods 1, p and p 12 which may be operated intermittently either so as to perform a simultaneous reciprocating movement in the same direction for the purpose of swinging the parts of the hanks. St which are to be dyed, in the bath, and so as to perform reciprocating movements in directions which are opposite to one another, at any giventime, for the purpose of wringing out or pressing the dyed parts of the hanks.

The swinging movement can be imparted suitable ad uStment of the arms of the cranks to the guide bars by the connecting rods in two ways.

In the first case the four connecting rods 72, p and 39 p engage with four crank pins A: mounted in similar peripheral positions on the shaft A, whereby when the shaft A is rotated all four guide bars F, F, F F are reciprocated so that they moveat anygiven time always in the same direction.

In the second case only the two connecting rodsp, p engage with the corresponding crank pins 72 and thereby actuate the two guide bars F, F directly, whilst likewise operating the guide bars F F indirectly by means of a coupling (not shown) so that they are reciprocated in similar manner. The connecting rods p p are thus eliminated in this way. a

If it is only desired to effect a to and fro movement but not a pressing operation, it is only necessary to employ rods, bars or the like, which are simply laid in position, and

also to employ two guide bars F, one on each side of the vat containing the dye bath.

If the rods 8 or the like are not simply laid in position but'are rigidly fixed to the guide bars, it is even possible to employ only one guide bar F.

For the purpose of effecting the movement for wringing or pressing, the two connecting rods p, p engage with the two crank pins k, is and the two connecting rods 19,, engage with the two crank pins 70,, In, which are displaced with regard to the crank pins 70,16 by an angle of 180, as a result of which when the shaft A rotates, the pairs of guide bars F, F and F F instead of moving at any given time in the same direction, move in opposite directions towards one another and thus cause the rods 8 to exert a pressing action.

The said pressing action can likewise be effected in two different ways, namely continuously or intermittently.

A continuous pressing action is obtained if the shaft A is put out of continuous operation by disengaging by means of a striking gear G the bevel wheel 1' mounted on the driving shaft M, and is turned by means of the hand lever H and the weighted'or spring controlled lever L to such an extent only that the pressing rods 8 operated by means of the connecting rods p and p and the guide bars F and F exert the necessary pressing action 011 the banks St.

The amount of the pressure can be ad-- justed as desired according to the amount of force exerted by hand or by the weight or spring action.

Intermittent pressing action is obtained if the shaft A is left in operation and the two crank pins acting on the connecting rods 72 are displaced towards k The pressing action can be regulated by k and k of'the connecting rods and guide bar connection and spring control (not shown) of the guide bars F and pressing members 8.

The swinging and pressing rods .9 can be inserted as required in the guide bars F and lifted out of the latter..

If the rods, bars or the like are not simpl inserted in the guide bars but are rigidly fixed therein, two guide bars, one on each side of the vat containing the dye bath, will be sufiicient for the pressing operation also.

Figs. .14 and 15 show a constructional example in which some of the swinging or pressing members 8 are fixed on a hollow shaft and the other swinging or pressing members are fixed on a shaft located within the said hollow shaft in such manner that the two shafts together with their rods 8 can be displaced in an axial direction and also turned through an angle of 90 independently of one another.

The hanks are'shown in the pressing position. The shafts C and D are actuated by means of slide rings from the two connecting rods p and 11 which are in turn actuated in the above-described manner by the cranks on the shaft A, which latter has been indicated on the drawing for space reasons at the upper part of Fig. 15 instead of below.

The two shafts C, D are adapted to be turned through about 90 so that all the rods carried on the said shafts can be rapidly brought into and out of the operative position, the necessary turning movement being effected, in the case of a small number of rods, by means of a hand lever and, in the case of a large number of rods, by means of a segment, worm wheel or the like.

Figs. 16 and 18 also show two shafts U, V carrying the rods 8, but in this case the shafts are not arranged within one another but side by side. The rods appertaining to the rear shaft U are provided with a curved portion whichpasses over the rods appertaining to the front shaft V, but the said first-named rods are shaped so that their ends are located when in the operative position in the same horizontal plane as that in which the rods appertaining to the shaft V are located. Both the shafts together with the rods carried by them are axially displaceable and can be turned through an angle of about 90.

In this constructional example the hanks are only shown in the pressing position in Fig. 16, the direction of movement of the connecting rods, shafts and pressing rods, corresponding to the pressing operation, beingindicated by means of arrows. Fig. 18 shows the hanks in the position which they occupy when being swung to and fro.

When broad vats and corresponding longer rods .9 are employed, the said rods should be of particularly strong construction or should be inserted in the guide bars on the side of the vat located opposite to the shafts U, V, in similar manner to that shown in Fig. 13.

The weighted levers X, Y serve for compensating the weight of the rods and for facilitating the rotation ofthe shafts U, V when the rods 8 are put out of action.

In the constructional form illustrated in plan in Fig. 17 the axial movement'of the shafts U, V, which are arranged side by side and carry the swinging rods .9, is not effected by means of a crank drive but by means of a cam drive, the pin J mounted on the shaft U engaging in a groove provided on a cam roller E fixed on the driving shaft M and the shaft V being entrained axially by means of the coupling 0 when the rods 8 move to and-fro.

If it is desired to effect a movement causing pressing action on the hanks, the two shafts U, V are not moved uniformly in the same direction but are moved in opposite directions, this being effected by means of suitable devices, for example similar to those shown in Figs. 13 and 15,or by other devices constructed differently but operated in similar manner.

The swinging rods appertaining to the shaft U pass over the shaft V in the manner, illustrated in Fig. 18.

For the purpose of causing the movement of the members, such as guide bars, shafts and the like, carrying the rods .9, in order to effect the swinging of the hanks, and the movement of the said members in opposite directions for effecting the pressing of the hanks, other mechanisms dependent upon lever action or inclined plane action, such as for example worm drives, eccentric drives and the like, may be employed instead of the devices above described which operate in the construction shown in Figs. 11 to 18 by lever action (crank drive, Fig. 11) or by inclined plane action (cam drive, Fig. 17).

It will be understood that the raising and lowering of the rollers \V from which the hanks are suspended can be effected in any suitable known manner as apart from the manner herein described.

The swinging rods 3 mounted in guide bars F, as illustrated in Figs. 11, 12 and 13, can be easily and rapidly inserted and removed without touching the suspension rollers W, which latter are always located above the said swinging rods.

The arrangement of the swinging rods or the like on axially displaceable shafts C, D, U, V, capable of turning through according to Figs. 14 to 18, also presents no obstacle to the operation of the rollers W inasmuch as the shafts can be displaced axially and then turned one after the other'through I an angle of 90 in such manner that the swinging rods 3 can easily pass between the rollers W.

The swinging and pressing devices for multiple dyeing of hanks of yarn described with reference to Figs. 1 to 20 therefore renderpossible a very compact arrangement of the suspending rollers-which is particularly advantageous inasmuch as it is thereby rendered possible to construct machines for the multiple dyeing of hanks of yarn, having a high efficiency and small dimensions.

By means of the present invention which provides new devices and methods of operation forthe multiple dyeing of the banks of yarn, all the requirements for multiple dyeing operations are advantageously met.
